How heat resistant is boron nitride
What is boron nitride?
Boron nitride is generally black, brownish or dark red crystals with sphalerite structure and also good thermal conductivity. Its solidity is second only to ruby, a superhard material generally used as device materials as well as abrasives. Boron nitride has chemical resistance and also no disintegration by inorganic acid and also water. The boron nitrogen bond is broken in hot, focused antacids. Oxidation begins in the air at 1200 ℃. Decay starts at about 2700 ℃ in a vacuum. It is somewhat soluble in warm acid and also insoluble in cool water. The loved one density is 2.29. The compressive toughness is 170 mph. The maximum service temperature level is 900 ℃ in the oxidation ambience and also 2800 ℃ in the non-active reduction ambience, but the lubrication efficiency is poor at room temperature. The majority of residential or commercial properties of boron nitride are much better than carbon materials. For hexagonal boron nitride: the rubbing coefficient is superficial Good high-temperature stability, excellent thermal shock resistance, high strength, high thermal conductivity, reduced development coefficient, high resistivity, deterioration resistance, microwave or infrared transmission.
What is the duty of boron nitride? Hexagonal boron nitride can make TiB2/BN composite ceramics, progressed refractories as well as superhard material; separation rings for continuous horizontal rolling, high-temperature resistant lubricating substances and also high-temperature coatings. It is additionally a resources for synthesizing cubic boron nitride. On top of that, it is also a very superb high-temperature lubricant, which can be made use of as a component of self-lubricating bearings. Boron nitride has many physical homes similar to graphite, called white graphite. It resembles mica, talcum powder, and also silicate; Fats are jointly referred to as white solid lubes. As a lubricant, boron nitride can be distributed in heat-resistant lubricating grease, water or solvent; It is splashed on the friction surface to create a completely dry film after the solvent volatilizes and afterwards completed the resin, ceramic, as well as metal surface area layers as a high-temperature resistant self-lubricating composite product. It is used in aerospace engineering, or the boron nitride powder can be directly coated on the overview rail surface. The boron nitride suspension oil is white or yellow. Consequently, it does not contaminate fibre products in fabric equipment and also can be extensively used in the lubrication of synthetic fibre fabric machinery.
Is Boron nitride damaging to body?
Boron nitride is not poisonous, yet boron nitride powder is a cloud of dust harmful to human health. Boron nitride powder is physically inert and will certainly be damaging to health when swallowed, breathed in, and exposured to the skin as well as eyes. Consuming or breathing in will certainly create skin, respiratory system, as well as kidney blood circulation problems.
Rate of boron nitride
Boron nitride bit dimension as well as purity will influence the product'' s cost, and the purchase volume can likewise impact the price of boron nitride. A huge quantity of huge amount will be reduced. The price of boron nitride can be located on our company'' s official web site.
